IMPRovBD MECHANIGAL MovEMIiNT.

To `all whom it 'may concern Be it known that we, HUGH THoMAs and. ROBERT WALLACE, both ofthe city, county, and 'State of New York, have invented a new and improved Mechanical' Movement; and we` do hereby declare 'that the followingis a fulhelear, and exact description of `the same, yreterence"belng. had to the accompanying drawing,-

forming part of this specitcation, and in which- Figure 1 is a longitudinal central section of our invention as applied'to screw-. braces;

in iig. 3; andi i v Figure 3 is a horizontal section on the'line y y, corresponding to 1.

- Similar letters'ot' reference indicate. corresponding parts in all the figures. i

,lhis invention consists in `a novel device for con# f vertilig-oscillating inotion'into rotary motion, and it l. et, B,1arge enough to ieceive'the This wheel is arrangedwithin a case, `lowed to rotate `therein ii'eely.

is 4applicable'to screw-braces, -ratchet-drills, screwjacks, and all machines in which a ratchet-motion is `eomfinonlyA used. l v i 'One ot' the principal features of this vdevice consists in means whereby it is made reversible by simply turning the handle or operating lever in its socket.

To enable others sk illedinjthe art to construct mechanical movementsin accordance. with our imreference to thezdrawiug.

2A is a wheel, `of any desirable size, having a suitable number of4 holes, a a, at equal distances from each other, formed on the periphery of` thesame, and which may be round, ,or ot' any other form.

B,.and isal- "l.he case B is made with a' ra'dial cxtensionor sockrod orlever C, and the spiral spring 1). i l. i l

.'lhe rod U passing through the socket B, enters the case' B far enough to drop into the holes'a a of the wheelA'.

A eoilar, c, keeps thelever C from dropping too far, 'while the spring l), around said lever, holds it down `with suliicient force to insure its .being always in gear with the wheel A.

`ZILherSchedule referred to in these Letters yPatent:

and making part ofthe same into the holes c a, is bevelled, so as 4to allow the lever to slip out of those holes when'moved in one direc.-V tion, and to rotate the wheel A when moved in the other direction, asclearly shown in iig. '2.

To make it reversible or inoperative, the lever C is further provided with a feather, e, to tit loosely into either of the grooves j' f1 f2 out into the screw-cap g,

- and maintain the lever C in a desired position.

makes it inoperative, the en'd o f the lever O being either direction.

the arrow, as shown in fig. 2,' the rod C is raised high enough to free the feather e from the groove, and

groove fl, when the lever G is dropped,and the feather e, fitting into the groove f1, holds it iu position.

rotates the wheel A, the straight side ot' its end acting againsty the wheel A, while the bevelled side allows it to slip out of the holes a. a, and bring the straight side again into action.

'lo rotate the wheel in the opposite direction, the lever O is raised vand turned halt' a revolution, when the feather' c will drop into the groove f2, and the bevsite direction, reverses the motion.

,To transmit the motion ofthe wheel A, `a screw, as

be applied,

VVhatis'here claimed, and desired to be secured -by Letters Patent, is

The combination, with the wheel A, of the case B, `having a radial extension, B', provided with grooves f f1 fz, the rod or lever G, fitting to the said socket, and having a bevelled inner end,and afeather, e, to Afit the v"grooves iu the socket, and the spring' D, the whole arranged substantially as herein described.
